NanoViricides Presents FluCide Data at 3rd Annual Influenza Research and Development Conference

NanoViricides, Inc. reports that its President, Dr. Anil Diwan, was invited to present the FluCide™ data at the 3rd Annual Influenza Research and Development Conference on Friday, July 11, at 0850 am.

The Conference ran from July 9-11 at the Hyatt Regency in Boston, MA, and was held by GTC Bio (

Dr. Diwan discussed the nanoviricides® technology platform, and presented the pre-clinical data on the Company's first drug candidate, NV-INF-1, Injectable FluCide™, to treat all influenza infections in hospitalized patients. Influenza A H1N1 infected animals treated with FluCide survived the full 21-day observation period, whereas animals treated with 40mg/kg/d oseltamivir phosphate (Tamiflu®) survived only 8 days in this highly lethal study. Influenza A/WS/33/ (H1N1) virus was used in this study. The highly lethal infectious dose of 1M viral particles at time 0 h followed by another 1M virus particles at 23h that was employed caused uniform lethality in 5 days in untreated mice. Body weight began to decline in the infected, untreated mice, by days 2-3 days and continued to decline until death. The Oseltamivir-treated mice maintained body weight only through day 5, which declined thereafter until death. Similar to the survival results, the mice treated with NV-INF-1 maintained their body weight substantially longer, through day 14. NV-INF-1 demonstrated an unparalleled 1,000-fold reduction in lung viral load compared to untreated animals on day 4 in this lethal animal model study. Moreover, the lung viral load was suppressed to this baseline level through 13 days or longer, with a slight increase on day 19. In contrast, the current standard of care, oseltamivir, (Tamiflu®, Roche) exhibited only a 2-fold reduction in lung viral load at day 4, that rapidly rose by approximately 2X on day 7. Similar to the reduced virus titers, on day 4 the lungs from mice that were treated with NV-INF-1 showed a substantially lower lung weight (healthy) and displayed a markedly reduced presence of virus-induced lesions as compared to the untreated control and oseltamivir. Also similar to lung virus titers, the reductions in lung lesions in animals treated with NV-INF-1 were maintained at least through 13 days.

Dr. Diwan also discussed the extremely high safety of NV-INF-1 observed in preliminary safety/toxicology studies. He noted that no significant changes in all observed parameters were found even at the maximum feasible dose of approximately 2,700 mg/kg/d repeatedly given for five consecutive days.

He also presented the data on NV-INF-2, the Company's current oral anti-influenza drug candidate. NV-INF-2 has the same antiviral ligand as NV-INF-1, but a different polymeric backbone that has enabled significant oral effectiveness. NV-INF-2 has been evaluated in a mouse model of influenza virus infection using two different influenza virus a strains, A/WS/33/ (H1N1) and A/W/67 (H3N2v). NV-INF-2 treated mice survived as long as 14.5 days in an H1N1 lethal infection study, and for 15.6 days in an H3N2 lethal infection study. Oseltamivir treated animals died in only 7.6 days in H1N1 infection study, and in 9.6 days in the H3N2 study. The lethal infection viral dose and protocol was chosen such that the untreated animals died in 5 days in both H1N1 and H3N2 studies. Similar to substantially increased survival, NV-INF-2 also exhibited substantially superior reduction in lung viral titer and protection of lungs from lesions.

The data indicate that both NV-INF-1 and NV-INF-2 are highly effective, broad-spectrum, anti-influenza drugs. The Company has shown that they are effective against both group I and group II influenza A viruses.

Dr. Diwan also reported that the Company is successfully scaling up production of NV-INF-1 for the GLP Safety/Toxicology study at its current facilities. In addition, he reported that construction of the Company's new facility capable of cGMP production of all of the Company's nanoviricides drug candidates for human clinical batches is now complete. Facility testing and validation are in progress.

The market size for an effective influenza drug for treating severely ill hospitalized patients has been estimated in the billions of dollars, worldwide, depending upon the therapeutic value and cost savings. Currently, there is no effective therapeutic available for this indication. The Company believes that it could supply a substantial portion of the demand for this drug from its new small scale cGMP clinical drug facility. This drug is currently in IND-enabling studies.

This broad-spectrum FluCide drug is expected to work against most, if not all, forms of influenza virus, including epidemic, pandemic (e.g. H1N1/2009), high path influenzas such as H3N2, H7N9, and "bird flu" such as H5N1.

The total market size addressed by the Company's current drug programs is estimated at about $50 billion. In addition to Injectable FluCide, the Company is working on five more commercially important drug candidates, namely: DengueCide™, HerpeCide™, HIVCide™, Oral FluCide™ for out-patients, and a broad-spectrum antiviral drug for viral diseases of the external eye. All of our programs are for therapeutics to treat viral infections. Our drugs are expected to be useful as prophylactics as well. DengueCide has recently received orphan drug designation by the US FDA as well as the European EMA.

NanoViricides recently received an important international award, the "IAIR Award 2014 for Leadership in Nanomedicines in the North American Sector".

The Company currently has approximately $41 million cash-in-hand and cash-like-instruments. These funds are estimated to be sufficient for taking at least one of our drug candidates through initial human clinical trials, and possibly take another drug candidate into human clinical trials.
